15 minutes earlier, when Alvine left Sylvia and the others because he was annoyed at not having been able to kill her enemy because of Sylvia's intervention... he slammed the door behind him with the note of his gravitational magic which was like a kind of telekinesis for him. He used this practical affinity almost every day in his daily life. To fly, to move animated and inanimate objects, or for good to isolate them as he had done with the king of the Elves by simply modifying gravity according to his desire.
